ABSTRACT

A surgical port includes a port body having a lumen extending therethrough and a plate having an opening. The port body may be made from foam. The port is configured such that rotation of the plate with respect to the port body aligns the opening and lumen defining a passage therethrough for the insertion of surgical instruments.

CROSS-REFERENCE TO RELATED APPLICATION

The present application claims the benefit of and priority to U.S. Provisional Patent Application Ser. No. 61/248,035, filed Oct. 2, 2009, the disclosure of which is herein incorporated by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to seals for use in surgical procedures. More particularly, the present disclosure relates to a seal anchor member adapted for insertion into an incision or opening in tissue.

BACKGROUND

Today, many surgical procedures are performed through small incisions in the skin, as compared to the larger incisions typically required in traditional procedures, in an effort to reduce both trauma to the patient and recovery time. Generally, such procedures are referred to as endoscopic, unless performed on the patient's abdomen, in which case the procedure is referred to as laparoscopic. Throughout the present disclosure, the term “minimally invasive” should be understood to encompass both endoscopic and laparoscopic procedures.

During a typical minimally invasive procedure, surgical objects, such as surgical access devices, e.g., trocar and cannula assemblies, or endoscopes, are inserted into the patient's body through the incision in tissue. In general, prior to the introduction of the surgical object into the patient's body, insufflation gasses are used to enlarge the area surrounding the target surgical site to create a larger, more accessible work area. Accordingly, the maintenance of a substantially fluid-tight seal is desirable so as to minimize or inhibit the escape of the insufflation gases and the deflation or collapse of the enlarged surgical site.

To this end, various valves and seals are used during the course of minimally invasive procedures. However, a continuing need exists for a seal anchor member that can be inserted directly into the incision in tissue and that can accommodate a variety of surgical objects while maintaining the integrity of an insufflated workspace.

SUMMARY

In accordance with various embodiments, the present disclosure is directed toward a surgical port having a compliant port body having at least one lumen extending therethrough. A plate may be moveably connected to the port body. The plate defines an opening that is selectively alignable with the at least one lumen. The surgical plate may be disposed in a substantial perpendicular relationship to the lumen. The plate may be rotatably moveable relative to the port body. The plate may be disposed on a proximal surface, a distal surface, or both surfaces of the port body. The plate may be movable through a discrete number of positions relative to the port body. When the plate is in a first position relative to the port body, all of the at least one opening of the plate is in complete alignment with the at least one lumen of the port body and when the plate is in a second position relative to the port body, less than all of the at least one opening of the plate is in partial alignment with the at least one lumen of the port body. The port body may be formed of foam.

In accordance with various example embodiments, the present disclosure is also directed towards a surgical port including a compliant port body having a lumen extending therethrough. The surgical port includes a plate rotatably disposed relative to the lumen, the plate defining an opening that, at least once in the plate's rotational path, is selectively alignable with the lumen so as to define a passage through the lumen and the opening for a surgical instrument. The surgical port may also include a first structure configured to facilitate rotation of the plate relative to a longitudinal axis of the port body. The first structure may comprise a pin. The surgical port may also include a second structure configured to maintain the relative position of the plate. The second structure maybe a shoulder disposed at the circumference of the plate which abuts a retaining shoulder on the body of the laparoscopic port. The plate may be located on a proximal surface of the port body. The surgical port may also include a second plate, and the second plate may be located on a distal surface of the port body. The plate and the second plate may be connected to each other so as to be moveable together relative to the port body. There may be multiple positions along a rotational path of the plate relative to the body such that a unique configuration of lumens therebetween is defined at each position. The plate may have a substantially arcuate convex profile. The plate may have a substantially arcuate concave profile. The plate may define an indentation along the circumference of the plate to facilitate rotation of the plate relative to the body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

While embodiments of the present disclosure are susceptible to various modifications and alternative constructions, certain illustrated embodiments thereof have been shown in the drawings and will be described below in detail. It should be understood, however, that there is no intention to limit the embodiments of the present disclosure to the specific form disclosed, but, on the contrary, the embodiments are intended to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the present disclosure as defined in the claims.

In the drawings and in the description which follows, in which like references numerals identify similar or identical elements, the term “proximal” will refer to the end of the apparatus which is closest to the clinician during use, while the term “distal” will refer to the end which is furthest from the clinician, as is traditional and known in the art.

With reference to FIG. 1, an embodiment of the presently disclosed access port is shown. The seal anchor member 100 includes a body 1 which is a temporary percutaneous implant configured to traverse the skin of a patient. Although the embodiment in FIG. 1 shows a percutaneous implant, it is contemplated that body 1 could traverse any biological barrier to provide selective communication between the volumes on opposing sides of the barrier. These include inter and intra organ barriers as well as systemic barriers within the body. It is further envisioned that the surgical port presently disclosed may be used in a naturally occurring orifice.

The body 1 of the access port has a generally cylindrical form with a proximal surface 9 having a first diameter 9D and a distal surface 10 having a second diameter 10D with a medial plane 11 having a third diameter 11D disposed therebetween such that third diameter 11D is less than second diameter 10D and first diameter 9D defining a profile which narrows near the medial plane and widens at the proximal surface 9 and distal surface 10, thereby defining a generally hourglass configuration. An example of an access port is disclosed by commonly assigned U.S. patent application Ser. No. 12/244,024, filed on Oct. 2, 2008 which is incorporated by reference in its entirety herein and illustrated in FIG. 1 a as seal member 500 extending through an opening W in body tissue T.

Although FIG. 1 shows proximal surface 9 and distal surface 10 as planar, it is contemplated that the profile of either surface could be arcuate such that the surface is concave to facilitate the placement of surgical implements and reduce the likelihood of tearing the surface when instruments are angulated or convex to facilitate the removal of fluid from the surface.

It is further contemplated that body 1 is composed of a substantially compliant or compressible material such that when body 1 is inserted into an incision, the tissue disposed along the sides of the incision compresses body 1 with the resultant restorative force between body 1 and the tissue defining a sealing pressure therebetween. The sealing pressure forms a substantially fluid tight seal with its surrounding tissue which separates the volumes which body 1 traverses, e.g. between an insufflated cavity and the extra-corporeal environment.

A plurality of lumens 3, 4, and 5 traverses body 1 parallel to a longitudinal axis “A.” Lumens 3, 4, and 5 may be configured to allow fluid communication between ends 9 and 10 or the insertion of surgical instruments (e.g. cannulas, trocars, endoscopes, etc.) therethrough.

As shown in FIG. 1, a plate 2 is disposed on proximal surface 9. Further, plate 2 and has openings 6, 7, and 8 extending therethrough.

As shown in FIG. 2 b, plate 2 may be rotated relative to body 1 about the longitudinal axis “A” to an “open” position wherein openings 6, 7, and 8 and lumens 3, 4, and 5 align defining passages therebetween.

As shown in FIG. 2 a, plate 2 may be rotated relative to body 1 about the longitudinal axis “A” such that the holes 6, 7, and 8 and lumens 3, 4, and 5 are configured in a “closed” position wherein no holes align with any lumen thereby obscuring the passage previously defined therebetween.

As shown in FIG. 2 c, plate 2 may be rotated relative to body 1 about the longitudinal axis “A” such that the holes 6, 7, and 8 and lumens 3, 4, and 5 are configured in a transition or intermediate position wherein holes 6, 7, and 8 partially align with lumen 3, 4, and 5 thereby partially obscuring the passage previously defined therebetween.

It is further contemplated that there may be a plurality of holes and lumens in a specific arrangement corresponding to a plurality of positions along the rotational path of the plate. When so configured, rotation of the plate relative to the body about the longitudinal axis “A” to each unique position defines a unique configuration of passages which traverse the port in terms of both number and location of the lumens. For example, the holes disposed the plate and body may be arranged in a pentagon centered at a position other than the longitudinal axis “A”. Consequently, if the plate is then rotated relative to the body about longitudinal axis “A”, there will be a first position in which two pairs of holes and lumens on the plate and body align defining two passages therebetween. Similarly, there will be a second position, in which a different hole and lumen on the plate and body will align defining only one passage.

It is further contemplated that there may be a spring or other biasing device disposed in the port 100 to bias the plate 2 toward a neutral position when no force is applied such that there is a passage between the plate 2 and body 1 in the neutral position.

Alternatively, there may be a spring or other biasing device disposed in the port 100 to bias plate 2 toward a neutral position such that when no force is applied holes 6, 7, and 8 and lumens 3, 4, and 5 do not align thereby obscuring the passage previously defined therebetween.

In an embodiment shown in FIG. 3 a, a body la has a stepped retaining shoulder 12 configured to abut a stepped ring 13 on a plate 2 a such that plate 2 a is retained relative to body 1 while being able to rotate relative to an axis parallel to a lumen 20 a.

It is further contemplated, as shown in FIG. 3 b, that a plate 2 b has a stepped retaining shoulder 15 configured to abut a stepped ring 14 on a body 1 b such that plate 2 b is retained relative to body 1 b while being able to rotate relative to an axis parallel to a lumen 20 b.

It is further contemplated, as show in FIG. 3 c, that a plate 2 c has an angled stepped retaining shoulder 17 configured to abut an angled stepped ring 16 on a body 1 c such that plate 2 c is retained relative to body 1 c while being able to rotate relative to an axis parallel to a lumen 20 c.

It is further contemplated, as show in FIG. 3 d, that there is a pin 18 which traverses plate 2 and a body 1 d such that a plate 2 d is retained relative to body 1 while being able to rotate relative to an axis parallel to lumen a 20 d.

It is further contemplated, as show in FIG. 3 e, that a body 1 e has a substantially conical or frustoconical protrusion 19 which traverses a plate 2 e such that plate 2 e is retained relative to body 1 e while being able to rotate relative to an axis parallel to a lumen 20 e.

It is further contemplated, as shown in FIG. 3 f, that a body 1 f includes a proximal plate 2 f having hole 8 f, a distal plate 21 having a hole 23, and a traverse pin 22, and a lumen 20 f. Traverse pin 22 couples the movement of distal plate 21 and proximal plate 2 f such that hole 23 is aligned with lumen 20 f when proximal hole 8 f aligns with a lumen 20 f defining a passage therebetween.

It is further contemplated that the axis about which plate 2 rotates is eccentric relative to plate 2 and body 1. It is further contemplated that, in various embodiments of the present invention, the seal anchor member 100 mat include multiple plates, each plate separately disposed so as to selectively cover and uncover different lumen, thereby providing a surgeon with additional flexibility, e.g., to cover a first lumen while leaving an instrument disposed within a second lumen, etc.

The use and function of seal anchor member 100 will be discussed during the course of a typical minimally invasive procedure.

Initially, the seal anchor member 100 is inserted into a tissue tract using known surgical techniques. Either subsequent or prior to the aforementioned insertion procedure, plate 2 on body 1 is configured in a first position, such that no holes on plate 2 align with any lumen disposed in body 1 thereby obscuring the lumen. In the course of this procedure, an operator may rotate plate 2 about the longitudinal axis “A” relative to body 1 into a second position such that one or more holes on plate 2 correspond to lumens on body 1 to define one or more passages therethrough. Thereafter, laparoscopic and endoscopic surgical instruments known in the art may be inserted into the lumen in order to carry out a surgical procedure.

During the course of the surgical procedure, an operator may replace or remove the instruments disposed in the port insert as needed.
